TTS is designing progression around observable evidence rather than time on a webpage. Knowledge, practical performance, field records, safety, and professional judgment must agree before a competency is recognized.
| Layer | Question | Evidence | What it does not prove |
|---|---|---|---|
| Knowledge | Can the learner explain the system and make the calculation? | Reviewed, randomized checks; source-based decisions; calculations with units and assumptions. | Physical task performance or field authority. |
| Practice | Can the learner follow the process in a controlled setting? | Simulations, schematics, fault stories, isolated trainers, worksheets, and instructor feedback. | Permission for unsupervised or regulated work. |
| Practical | Can the learner perform and verify the task? | Observed rubric, equipment state, measurements, acceptance criteria, documentation, and restoration. | Licensure, employer qualification, or OJL hours. |
| OJL | Can the learner repeat the work across real conditions with increasing independence? | Authorized supervisor sign-off, hours, task variety, quality, safety, rework, and field evidence. | Automatic apprenticeship completion or independent authority. |
When activated after validation, reviewed forms and answer keys remain private. The platform issues the form, validates completeness, scores it, applies critical-item rules, limits attempts, and records an auditable result.
The assessor records equipment state, prompts, measurements, acceptance results, restoration, and any critical failure. A quiz cannot substitute for a physical skill.
Written results, calculations, practical work, OJL distribution, mentor evaluations, quality, remediation, and remaining supervision needs are reviewed together.
Unauthorized work, defeated safeties, unsuitable instruments or PPE, hazardous equipment state, false records, or failure to verify restoration can stop an attempt and require remediation even when other answers are correct.
Verified learner and employer; date, site/project context, program, task category, supervision level, and authorized mentor identity and role.
Specific task verbs and scope, equipment/system context, hazard controls, source documents, learner role, and measurements or evidence references.
Result, quality check, rejected or reworked items, stop-work events, restoration, and the as-left condition.
Supervisor attestation, learner reflection, remaining supervision, remediation, and the next-period task and coaching plan.
Program status, high-level curriculum maps, field-team biographies, learning philosophy, selected approved figures, and launch disclosures.
Full lessons, assessment forms, answer keys, editable drawings, student identities, grades, OJL evidence, signatures, payments, staff tools, and security configuration.
Least-privilege access, MFA for staff, server-owned scoring, audit records, backups, monitoring, incident response, and tested recovery are required before activation.
No website can be guaranteed impossible to compromise. TTS will describe the safeguards it actually operates, keep sensitive features disabled until they are tested, and never claim ISO certification or guaranteed protection without the required evidence and independent process.
